yellowcode and H323 gateway with multiple connections...

[andres.pasten]

Hi,

On other discussions has appeared a case of Yellowcode alarm on CCM cluster, and related to a gateway generating multiple calls. I have that issue, and solved it using max-conn to limit the quantity of connections to the CCMs, but I found that the dial-peer matching the issue is announcing that the max-conn is exceeded, but with no call present using it.

A sample:

R3825ToescaP2#sh voice call stat
CallID     CID  ccVdb      Port        DSP/Ch  Called #   Codec     Dial-peers
0x596184   2C1C 0x70BCE668 0/3/0:15.7  0/1:4   6015       g711ulaw  200/611
0x59618B   2C1E 0x70BCE668 0/3/0:15.8  0/1:2   6519       g729r8    200/650
0x596198   2C22 0x70BCE668 0/3/0:15.15 0/2:1   6090       g711ulaw  200/611
0x5961A2   2C27 0x70BCE668 0/3/0:15.12 0/1:5   6134       None      200/612
0x5961A6   2C29 0x70BCE668 0/3/0:15.11 0/1:1   6034       None      200/611
0x5961A8   2C2A 0x70BCE668 0/3/0:15.24 0/1:3   6173       None      200/612
6 active calls found

*Dec  6 18:47:50.100: %CALL_CONTROL-6-MAX_CONNECTIONS: Maximum number of connections reached for dial-peer 610

So no active call is matching DP 610, but the warning for maximum number of connections is present.

This is the config:

dial-peer voice 610 voip
tone ringback alert-no-PI
preference 1
max-conn 60
destination-pattern 60[012346789].
progress_ind setup enable 1
voice-class codec 10
voice-class h323 1
session target ipv4:172.30.1.2
incoming called-number .
dtmf-relay h245-alphanumeric
no vad
!

dial-peer voice 611 voip
tone ringback alert-no-PI
preference 2
max-conn 60
destination-pattern 60[012346789].
progress_ind setup enable 1
voice-class codec 10
session target ipv4:172.30.3.2
incoming called-number .
dtmf-relay h245-alphanumeric
no vad
!

Any idea of what could be happening on this situation?

ok, it have c3825-spservicesk9-mz.124-9.T7.bin, it's the last of that version, so I´ll try with c3825-spservicesk9-mz.124-15.T14.bin, and let you know...

Hi,

I´ve made the upgrade of the IOS, but the messages announcing the max-conn exceeded are still present. The CPU is controlled anyway.

Dec 15 18:17:33.758: %CALL_CONTROL-6-MAX_CONNECTIONS: Maximum number of connections reached for dial-peer 619
Dec 15 18:17:33.790: %CALL_CONTROL-6-MAX_CONNECTIONS: Maximum number of connections reached for dial-peer 619
Dec 15 18:17:33.790: %CALL_CONTROL-6-MAX_CONNECTIONS: Maximum number of connections reached for dial-peer 611

The E1 controllers are ok.

It seems that the upgrade of IOS solved the issue about teh CPU, but I'm worried about the origin of this multiple connections that are present on this gateway.

Any idea?
